In mobile computing systems, predicting the next location of a mobile wireless user has gained interest over the past decade. Location prediction may have a wide-range of application areas such as network load balancing, advertising and web page prefetching. In the literature, there exist many location predictors which are divided into two main classes: domain-independent and domain-specific. Song et al. compare the prediction accuracy of the domain-independent predictors from four major families, namely, Markov-based, compression-based, PPM and SPM predictors on Dartmouth's campus-wide Wi-Fi mobility data. As a result, the low-order Markov predictors are found as the best predictor. In another work, Bayir et al. propose a domain-specific location predictor (LPMP) as the application of a framework used for discovering mobile cell phone user profiles. In this thesis, we evaluate LPMP and the best Markov predictor with Dartmouth's campus-wide Wi-Fi mobility data in terms of accuracy. We also propose a simple method which improves the accuracy of LPMP slightly in the location prediction part of LPMP. Our results show that the accuracy of the best Markov predictor is better than that of LPMP in total. However, interestingly, LPMP yields more accurate results than the best Markov predictor does for the users with the low prediction accuracy.

Explainable Security in SDN-Based IoT Networks Sarica, Alper Kaan; Angın, Pelin (2020-12-01) The significant advances in wireless networks in the past decade have made a variety of Internet of Things (IoT) use cases possible, greatly facilitating many operations in our daily lives. IoT is only expected to grow with 5G and beyond networks, which will primarily rely on software-defined networking (SDN) and network functions virtualization for achieving the promised quality of service. The prevalence of IoT and the large attack surface that it has created calls for SDN-based intelligent security solut...
Energy-Aware Data Delivery Framework for Safety-Oriented Mobile IoT Al-Turjman, Fadi (2018-01-01) The proliferation of wireless multimedia sensor networks has given rise to intelligent transportation systems as a mobile data-sharing model. This vision can be extended under the umbrella of the mobile Internet of Things to include versatile resources, such as smartphones, radio frequency identification tags, and sensors on roads that can be utilized in emergency situations. The facilitation of such a vision faces key challenges in terms of interoperability, resource management and energy consumption. In t...
An Overview of Internet of Things and Wireless Communications ULUŞAR, ÜMİT DENİZ; Al-Turjman, Fadi; Celik, Gurkan (2017-10-08) Innovations in technology that have enabled efficient wireless tiny devices propelled the concept of Internet of Things. It is expected that mobile data traffic will experience 8-fold growth between 2015 and 2020 and the number of mobile connected devices will reach 11.6 billion by 2020. Main factors of this exponential growth and wide acceptance are the integration of several technologies and communications solutions such as wired and wireless sensor and actuator networks, next generation communication pro...
Instrumented monitoring and dynamic testing of Metu cable stayed pedestrian bridge and comparisons against analytical model simulations Özerkan, Taner; Türer, Ahmet; Department of Civil Engineering (2005) This study includes structural instrumentation and monitoring of a 48.5 meters long cable-stayed pedestrian bridge located on Eskişehir road near METU campus. The objectives of the study are (1) to monitor the bridge responses during erection and operation stages so that the strain changes are determined during important events such as transportation, lifting, cabling, mid-support removal, slab concrete pouring and tile placement, (2) to determine existing cable forces using vibration frequencies, and (3) c...
Smart Neighbor Scanning with Directional Antennas in 60 GHz Indoor Networks Olcer, Gencay Mutlu; Genc, Zulkuf; Onur, Ertan (2010-09-30) The 60 GHz technology has an immense potential to provide wireless communication at multi-gigabit rates. At 60 GHz frequency band, severe attenuation of the signals can significantly degrade communication performance. To cope with the attenuation problem, directional antennas with high directive gains can be utilized. When network nodes use directional antennas, the neighbor discovery process becomes more complicated and time consuming. To reduce the neighbor discovery time, we propose a smart neighbor scan...
